Timelapse of the ~16” of snowfall Sunday and Sunday night in Acton, MA @wx1box.bsky.social #mawx

Something truly amazing about this storm in New England is the pure depth of the DGZ during the first half of the event. Nearly 4 km deep with almost full overlap with the best vertical motion. This is remarkable and will lead to our 2-3 in/hr rates for several hours later today #mawx

Now that’s a lot of different cloud types!

Today marks 10 years since I defended my dissertation. According to AMS, I am now mid-career. Yikes!

Last night’s sunset via drone #mawx

Aaaaand we ended up in the basement while rotation went directly overhead. Tornado to our southwest just beforehand. We’re good.

Classic OU football fan, news tornado break-in and all #mawx #boomer

“I am sorry, you do not get to have it both ways: you cannot say “this is the most dangerous river valley in the United States” and then act like what happened was a total shock.”

Why on earth is @npr.org only quoting posts on X in this timeline? Do they think that is the only way people receive weather information and warnings? The weather enterprise has worked tirelessly for decades to avoid this type of nonsense worldview and provide MANY sources to receive these warnings.

Acton, MA 4:09 PM on 6/23/2025. 97/81 for a heat index of ~120F. Absolutely unbelievable. @wx1box.bsky.social

Absolute insanity Dickens Nebraska tornado a bit ago at close range! Right off the iPhone lens spots and all!

Career tornado intercept just now Dickens Nebraska!

And you told your kids Sharknado was just a movie…

Here are some of the data movies we made from the AIR's deployment on the Canadian, TX tornado 10 years ago today. Absolutely unbelievable resolution. The RHI sweep (see thread) is in real-time, demonstrating the ability to collect extremely high-temporal-resolution volumes.

It's been 10 years since the Canadian, TX tornado that capped my dissertation and made our BAMS cover article on the Atmospheric Imaging Radar possible. We collected data at 6-km range, capturing full volumes of the tornado's dissipation stages every 7 seconds. doi.org/10.1175/BAMS...

53.4F 60 minutes ago, now 38.2F and snowing. Weather is cool.

Just some garden variety 45-dBZ convection with embedded lightning... at 29.4F and plummeting. Absolutely pouring ZR. It's been a day, that's for sure.

After a couple of years of mostly collecting dust, the snowblower has been getting a serious workout over the past few weeks. No blockbusters, but the storms are adding up. This time I made a path for the generator in the side yard given the expected winds tonight and tomorrow.

Obligatory “it’s cold” post from Acton, MA. Yikes.

Finally made it to SLS, with a first class upgrade to boot. This venue is incredible. Better late than never!

It’s nice to see all of the folks coming over here in the past couple of days! I’ll celebrate the hopeful re-gathering of our weather community with (gasp!) a comet picture!

What we really need...

Looks like we’re getting some anthropogenic snow bands out by DIA right now.

Saw a couple of bobcats in the back yard this morning! So beautiful!
